FASTENING-INSERTING MACHINE.

Application filed June 3,

1 0 all rv/um it may concmm Be it known that I, Fnnn L. MACKENZIE, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Fastening-Inserting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for inserting fastenings and has for its object improving the organization of such machines better to adapt them for operating upon work of varying characteristics.

The invention will be hereinafter described, by way of example, as applied to,

thereon by the driverand awl and clamps it normally against the foot plate of the ma- The horn is lowered intermittentlv for brief intervals to ainclamp the work and to permit it to be fed by the awl. 'The work positioning mechanism of such machines commonly comprises a which contacts with the edge of the work adjacent to the point of penetration of the work by the awl and is mounted for movement transversely of the edge of the work and substantially in line with the awl when in position to penetrate the work. In the operation of the machine, the work is maintained against the gage by the operator, and when the gage is moved forwardlygi. e. in the direction of the work, itnecessaril thrusts the work forwardly. Consequently, forward movement of the gage is permitted only when the portion of the work contacted by the gage is free to move. During the larger part of the cycle of operations of the machine, how ever such portion otthe work is held against movement due to the work being clamped between thefoot plate and'the horn on to the Specification of Letters Patent.

promotion of the awl into the work in the path of movement of the gage. ,It is only during the relatively small part of the cycle of operations of the machine in which the awl passes through the final stage of its feedlng movement after havingbeen withdrawn from the path of movement of the gage that forward movement of the work and gage is allowed. a

In the employment of the machine on many kinds of work, for example, in the manufacture of shoes of certain styles, it is necessary to move or adjust the gage during the operation of themachi'ne on asingle piece of work; The adjustmentof the edge gage is effected without checking the operation of the machine, and has heretofore, so far as applicant is aware, been manually performed. Inasmuch as these machines operate very rapidly and the edge gage is capable of adjustment in the direction of the work during a small part only of the cycle of operations of the machine, the operator must act very quicklyto effect complete'adgust-ment of the gage at the desired point of the work. It results frequently that the operator effectsonly an incomplete adjustment of the gage in the short space of time permitted for the operation, thus causing uneven work. I

'In carrying out the objects of this invention, the above and other disadvantages attendant upon present methods of adjusting the edge gage have been obviated. by the provision of improvedpower operated means for effecting the adjustment of the gage relatively to the plane of operation of, the

fastening inserting mechanism, so as to vary the distance by WhlCh the row of. fastenings is spaced from the edge'of the work. In the illustratedembodiment of the invention, the '1.

spring will be relieved from the work during the remainder of the cycle of operations, the spring being rendered operative on the gage, however, at intervals of the succeeding cycles of operations, so that complete forward adjustment of the ga e when once in itiated is assured. The a justment of the gage both toward and from the plane of operation of the fastening inserting mechanism is initiated by a manually controlled member-operabl at any time in the operation of the machine to effect adjustment of the gage at the proper predetermined time in thecycle of operations of the machine.

In operating on certain classe'sof work it isparticularly desirable to move theedge gagetoward or fromthe plane QfOpBIElt-IOD of hefastei'iing inserting mechanism at the same time, that a change is made in the characte of the fastenings inserted by the machine. For instance, it is common for the welt or outsole to be extended further oiit from the marginfof the insole at the forepart of the shoe than in. the shank, and

' itis also desirable, by reason of the greater wear on the ball portion of the sole and the greater thicknessof stock atthe ball portion offthe shoe an'dlat the toe, to insert longer fastenings in the forcpa'rt than in the shank. Accordingly, another. feature of invention resides in the rovision of improved automatic means or moving the cdgegage from one position of adjustment toanother and alsochanging the character of fastening inserted by the machine.

Although the embodiment of the inven tion now preferred by ne isherein described and illustrated as a plied to a machine for inserting string nai 5 having an awl feed,

it is recognized that the invention is not re st-ricted in its applicatlon to string nalllng machines nor-to. machines characterized by an aw] feed,;but is caable of use with fastening inserting mac ines of other types.

1 ment; and

Moreover, the invention in certain of its aspects is not restricted to the specific mechanism herein shown and described but is capable of embodiment in other forms without departingfrom the principles of the invention. It is thereforeintended that the scope ofthe invention shall be limited only as. required by the claims.

Otherobjects and features of the invention will appear as the'description proceeds and will be pointed out in the appended claims. a x

In the drawings, a a

Figure 1 is aview in elevation :of a fastening inserting .machine with the invention applied thereto; 1

'Figr2 is aview in elevation showing the power operated means for moving the edge gage to its different positions, otadjust- Fig. 3 is a view in detail of the connections through which motion is transmitted to the edge gage.

The machine comprises a swinging head 2 carrying fastening inserting mechanism embodyin a driver (not shown) and an awl 4. llfiition is transmitted to the awl in a direction to cause the same to penetrate into the work by means of an arm 6, carrying a cam roll which engages a cam groove in the cam 8, the connections from the arm 6 to the awl being preferably of the character fully shown and described in the application of Fred L. Mackenzie, Serial No.

I 137,152, filed December 15, 1916. The head 2 is moved laterally during the time the awl is in the work to effect feeding movement of the work by an arm 10 mounted on a shaft journaled in the frame of the machine, and actuated by an arm 12 controlled in its movements by the cam 8.

Means are provided for changing the character of the fastening inserted by the machine, as, for example, effectuating a change from shorter to longer fastenings or vice versa. Such means comprises an oscillating member 14 having impact surfaces 16 and 18 on opposite sidesof its axis and an impact member in the form of a plunger 20, the path of movement of which is capable of being changed, so that it may impart a blow against either of-the' impact surfaces 16 and 18 and thereby change the character of fastening inserted bythe machine. The plunger 20 is connected to and operated from, the arm 6, and, inasmuch as the arm 6 effects the work penetrating movement of the awl, it will beunderstood from the i'o-re-.

going that the oscillating member 14: is

shifted simultaneously with the penetration of the plunger '20 and thus effect a change I in the character 0i. fastening being inserted,

a bell-crank lever 22 is operatively connected to the plunger 20, said bell-crank lever being pivoted at 24; on a bracket 26 carried by a stud 28 fixed in the frame of the machine. The bell-crank lever 22 is con I nected to a link 30' pivoted at 32 on the bracket 26, said link 30 being provided with a spring-pressed plunger 7 (not shown) which operates to retain the bell-crank lever in position whether; it be moved to cause the plunger 20 to align with the impact surface 16 or 18. By reference to Figs. .1 and 2, it will be seen that when the bell-crank lever 22 is moved to align the plunger 20 with the impact surface 18 of the oscillating member 14, the connection between the bell-crank lever'22 and the link 30 ismoved below the line of their pivotal points 24: and 32, whereas, whenthe bell-crank lever 22 is moved to align the plunger 20 with the impact surbell-crank lever 22 and the link 30 is moved whereby the plunger 38 is caused to engage with the inclined surface 66 ot the latch 56 and i'ree the edge gage from the restraint of said latch simultaneously with the penetration of the work by the awl. From the foregoing it will be understood that. as the horn is depressed and the work fed subsequent to the penetration oi the work by the awl, the springs 46 and 54 are rendered operative to thrust the edge gage 36 against the work and to push the work forward upon movement of the aw] toward the line of d rive oi the fastenings. la the continuance ot the operation of the machine, the plunger 38 is raised from engagement with the latch 56 substantially simultaneously with the re clan ipiiugof the Work between the horn and foot plate of the machine. \Jllil'fillllfill the spring 60 presses the teeth of the latch 56 into engagement with the teeth of the ar zi 42. If it should occur that the spring 7 and 54 do not move the edge gage to its Full limit of adjustment during thecycle of operations oi? the machine in which the springs are first rendered operative to move the gage, the teeth of the latch 56 will engage the teeth of the member 42 upon the reclampina' of the work between the horn 52 and the loot plate, and will thus release the work from the pressure ot the springs. Moreover,11p0n the next cycle of operations of the machine the plunger 38 will again engage the in clined surface 66 of the latch 56 and will renderthe springs 46 and 54 again o ienatire on the edge gage. It is thus manifest that when the adj ustmentof the edge gageis once initiated, the movement ot the edge gage to its final limit of adjustment is assured.

In the foregoing specification, as also in the appendedclaims, reference is somet' made to the plane of operation ot the tening inserting mechanism. In the 1nachine to which the invention isx shown as applied, such plane of operation may be taken as that passing through the awl and the driver. It is tobe understood, however, that the invention is not limited to a'n'iachine' having an awl feed and as applied to a muchine which is not providedwith an owl or with feeding means 'of any nature, such plane is assumed to be substantially that passing through the line of drive of the t'asmechanism for inserting metallic fastenings,
